Assembly
6 Requirements
The unit must not be set up or operated
within the vicinity of the patients (within a
radius of 1.5 m).
The unit can be installed either at the same level
as the surgery room or on a floor below (e.g. cel-
lar).
Due of the amount of noise generated, we rec-
ommend that the unit is installed in an adjoining
room.
The pipes provided on-site must at least meet
the country-specific requirements for drinking
water.
Further information can be found in our
separate planning information leaflet for
compressed air.
6.1 Installation/setup room
The room chosen for set up must fulfil the follow-
ing requirements:
– Closed, dry, well-ventilated room
– Should not be a room made for another pur-
pose (e. g. boiler room or wet cell)
– If the unit is installed in a machine room, e.g. in
an adjoining room or cellar, the requirements
set out in ISO‑TS 22595 must be complied
with.
NOTICE
Risk of overheating due to insufficient
ventilation
The units generates heat. Possibility of
heat damage and/or reduced service life
of the unit.
❯Do not cover the unit.
❯Install a fan for auxiliary ventilation in
rooms where ambient temperatures
exceed ³40 °C while the unit is in
operation.
≥ 40 °C
6.2 Setup
The following conditions must be taken into
account for installation:
The air is filtered when it is sucked in. This
does not alter the composition of the air.
For this reason it is important to keep the
sucked-in air free of harmful substances
(e.g. do not suck in exhaust gases or
contaminated exhaust air).
– Clean, level and sufficiently stable subsurface
(note the weight of the unit).
– Type plate easy to read.
– Unit easy to access for operation and mainte-
nance.
– Easy-to-access power outlet to which the unit
is connected.
– Maintain sufficient distance to the wall (at least
20 cm).
– The compressed air pipe should be routed as
closely as possible to the place of installation
(note the length of the hose supplied).
6.3 Information about electrical
connections
❯Ensure that the electrical connections to the
mains power supply are established in accor-
dance with current valid national and local reg-
ulations and standards governing the installa-
tion of low voltage units in medical facilities.
❯Observe the current consumption of the
devices that are to be connected.

7 Transport
WARNING
Risk of explosion of the pressure tank
and pressure hoses
❯The pressure tank and the pressure
hoses must be vented before they are
stored or transported.
❯Protect the unit against moisture, dirt and
extreme temperatures during transport ("4
Technical data").
❯Always make sure that the condensate collec-
tor chamber is empty before transporting the
unit ("14 Taking out of use").
❯Always transport the unit in an upright position.
❯Only transport the unit using the transport han-
dles provided.
❯Check the unit for transport damage.
8 Installation
8.1 Establishing the compressed
air connection
The supplied flexible pressure hose
between the pipe system and the com-
pressor prevents vibrations from being
transmitted and thus reduces noise. This
ensures safe and reliable operation.
❯Connect the pre-assembled connecting sleeve
of the pressure hose to the quick release cou-
pling.
❯Measure the required length of the pressure
hose and shorten if necessary.
❯Press a fitting hose connector (not included in
the scope of delivery) onto the pressure hose
(internal diameter 10 mm) and secure it with a
hose clip.
❯Connect the connecting sleeve of the pressure
hose to the compressed air tube.
8.2 Place a collector tray under-
neath
During operation, condensation water on the unit
is continuously separated and automatically
drained. In order to prevent water damage due to
Assembly
14 5286100072L02 1909V005
EN

drained condensation, it is collected in the collec-
tor tray.
As an option, the condensation can also
be drained through a hose into the waste
water system. Always comply with appli-
cable national regulations for waste water
systems.
❯Place a collector tray under the condensate
separator or the membrane drying unit
(depending on type).
8.3 Network connection
Purpose of the network connection
The network connection is used to exchange
information or control signals between the unit
and a software installed on a computer, in order
to, e. g.:
– Display parameters
– Select operating modes
– Indicate messages and error situations
– Change unit settings
– Activate test functions
– Transmit data for archiving
– Provide documents concerning the units
During initial installation, a router or server
with DHCP is recommended so the unit is
detected in the network.
❯Plug the network cable into the control and into
a network socket.
❯Establish a connection to the computer net-
work using the network cable.

1 Network cable
8.4 Electrical connections
Safety when making electrical connections
The unit has no main power switch. For
this reason it is important that the unit is
be set up in such a way that the plug can
be easily accessed and unplugged if
required.
❯The unit must only be connected to a correctly
installed power outlet.
❯Make sure that none of the electrical cables
leading to the unit are under any mechanical
tension.
❯Before initial start-up check that the mains sup-
ply voltage and the voltage stated on the type
plate match (see also "4. Technical data").
Establishing the electrical connections
DANGER
Risk of electric shock due to defective
mains cable
❯Mains cables must not be allowed to
come into contact with any hot sur-
faces on the unit.

cific mains plug
8.5 Two devices in a single com-
pressed air network
With the compressor it is possible for two units to
be connected to a single compressed air net-
work. To do this,
– the pressure vessels need to be connected to
each other;
– the controllers of the compressors need to be
connected to each other;
– the controllers need to be set up accordingly.
Connecting pressure vessels
If two devices are connected to a single com-
pressed air network, pressure equalisation must
take place between the pressure vessels. To do
this, the pressure vessels need to be connected
to each other.
So that the pressure can be equalised, no
non-return valves must be installed
between the pressure vessels.
MAIN AUX
1 Main device (MAIN)
2 Auxiliary device (AUX)
CAN bus for main device / auxiliary device
Before connecting or disconnecting the
network cable, switch off the device and
make sure it is not connected to the
power supply (e.g. disconnect the mains
plug).
If two devices are connected to a single com-

municate with each other. To do this, connect the
CAN bus interfaces to the controllers with a net-
work cable and set one of the controllers to
MAIN, the other to AUX.

9 Commissioning
❯Before taking the unit into operation, check for
any damage. Damaged units must not be
used.
In many countries technical medical prod-
ucts and electrical devices are subject to
regular checks at set intervals. The owner
must be instructed accordingly.
❯Turn on the unit power switch or the main
surgery switch.
❯Carry out an electrical safety check in accor-
dance with applicable local regulations (e.g. the
German Ordinance on the Installation, Opera-
tion and Use of Medical Devices / Medizinpro-
dukte-Betreiberverordnung) and record the
results as appropriate, e.g. in the technical log
book.
9.1 Checking the switch-on/cut-
off pressure
The switch-on/cut-off pressure is preset at the
factory. Check the adjustment during first start-
up.
When the mains plug is connected the compres-
sor will start up after a delay of 10 s. If the com-
pressor was in standby mode before it was last
taken out of operation, then it will be in standby
mode again after the mains plug is connected.
❯Read off the cut-off pressure from the pressure
gauge.
❯Drain the air from the pressure tank (e.g. via
the condensate drain valve) until the unit starts
and then close it again.
❯Read off the pressure when the unit starts up.
Result:
If the readings deviate from the values preset at
the factory, adjust the values to a different
required pressure if necessary.
9.2 Checking the safety valve
Correct operation of the safety valve must be
checked when the unit is started up for the first
time and again subsequently at regular intervals.
At the factory, the safety valve is set to
10 bar (1 hPa), checked and stamped.

DANGER
Risk of explosion of the pressure tank
and pressure hoses
❯Do not change the safety valve set-
tings.
❯Fill the pressure tank to the cut-off pressure.
WARNING
Risk of damage to the safety valve
Risk of explosion of the pressure tank
and pressure hoses due to a defective
safety valve
❯Do not use the safety valve to vent the
pressure tank.
❯To open, rotate the screw of the safety valve
anti-clockwise until the valve begins to blow
off. Only allow the safety valve to blow for a
short period.
❯Then turn the screw clockwise as far as it will
go to close the valve. The valve must now be
closed again.
9.3 Draining the condensation
water
Temperature changes during transport may
cause condensation water to accumulate in the
pressure tank. The condensation water can only
be drained from the pressurised pressure tank.
❯Start up the unit and wait until the cut-off pres-
sure is reached.
Pressure tank
❯At maximum tank pressure, slowly open the
condensate drain valve.
❯Close the condensate drain valve as soon as
all of the accumulated condensation water has
been blown out.
9.4 Monitoring the unit via the
network
The following requirements must be met in order
to monitor the unit on the computer:
– Unit connected to the network
– Current monitoring software installed on the
computer
